Ishoy, Hartford, Mich., assignors to Whirlpool Corporation, a corporation of Delaware Filed Dec. 30, 1960, Ser. No. 79,641 13 Claims. (Cl. 74-157) This invention relates to a regulator Iand more particularly to a water meter regulator.
In one improved form of water meter re-gulator, for use in water softening systems, a ratchet wheel is rotated by a driving pawl mounted on an oscillating lever for movement therewith, and pivotable thereon between two positions for driving the ratchet lwheel selectively in opposite directions. A holding pawl is concomitantly pivotable with the driving pawl ybetween two positions for selectively engaging and regulating the ratchet wheel for step-by-step movement. During movement between its two positions the holding pawl actuates `a control device, such as an electric switch. The driving pawl may be moved between its two positions in any suitable manner responsive to a predetermined amount of rotation of the ratchet wheel. The mechanism lfor moving the pawls between their two positions, however, has been of .a cornplicated and expensive construction. A primary `feature of this invention is the provision of a simplified mechanism for effecting concomitant movement of the driving and holding pawls between the two positions thereof.
An important feature of this invention is the provision of a new and improved over-center spring connection with the driving pawl and the holding pawl for moving the holding pawl between two positions in response to movement of the driving pawl between two positions.
Another feature of this invention is the provision of a regulator in which a lever oscillates on a base, having a driving pawl mounted on the lever for movement beltween two positions for selectively engaging and moving a ratchet -wheel in opposite direction on the base responsive to oscillation of the lever, la holding pawl mounted on the base for movement between two positions for selectively engaging and regulating the movement of the ratchet wheel, 'and a spring having portions connected to the pawls and responsive to movement of the driving pawl between the two driving pawl positions for moving the holding pawl Ibetween the two holding pawl positions and for urging the pawls into engagement with the ratchet wheel.
Other features and advantages of the invention will be apparent from the illustrative embodiment of the invention shown on the accompanying drawings. Of the drawings:
FIGURE 1 is a plan View of a regulator -with parts thereof in one of two positions;
FIGURE 2 is a partially diagrammatic vertical section taken substantially along the line 2 2 of FIGURE 1; and
FIGURE 3 is a fragmentary plan view, similar to FIG- URE l, but with the parts in the other of the two positions.
The invention is, in brief, directed to a regulator having a ratchet wheel 25 rotatably mounted on a base 12 and driven by a driving pawl 36i pivotal on an oscillating lever 16. The driving pawl 30 is movable between two positions for selectively engaging ratchet teeth 27 on wheel 25 to drive the ratchet Wheel selectively in opposite directions in response to oscillating movement of the lever 16. A holding pawl 43 -is pivotal on the base 12 for movement between two positions, each corresponding to opposite positions of the driving pawl 30', for reg-ulating the ratchet wheel 25 for step-by-step movement by the driving pawl 30, and for reversing a control mecha- ICC nism 50 in response to movement of the holding pawl 43 between its two positions. yIn response to a predetermined amount of movement of the ratchet wheel 25, an abutment 36 on the ratchet wheel 25 engages a cooperating abutment 35 on the `driving pawl 30 for reversing the position of the driving pawl, `and concomitantly with reversal of the driving pawl 301, .a C-shaped over-center spring 57 having opposite ends 58 and 59 pivotally connected to portions of the drivin-g pawl 30 and the holding palwl 43 moves the holding pawl to its other position, thereby reversing the control mechanism 50. Whenever the ratchet wheel has been rotated a predetermined amount the control mechanism is reversed. Herein, the invention is described -as applied to a water meterregister for alternating the flow of water as between two water softening tanks, responsive to a predetermined quantity of water flowing through each tank.
Referring to the drawings, in FIGURE 2 the water meter 10 includes a housing 11 containing the base 12, in the form of .a plate, irmly secured therein as by bolts 13. As seen in FIGURES 1 and 2, .a main pin 14 is suitably attached to the base as -by a peened portion 15 and extends upwardly from the base. Oscillating lever 16 on the base 12 has an end pivotally mounted on the main pin 14. Means responsive to the flow of water through the water meter for oscillating the oscillating lever 16 is provided in the form of a gear 17, interconnecting an eccentric 18 and a suitable lluid motor (not shown) for driving the `gear train an amount corresponding to the volume of water passed through the motor. The eccentric 18 has a cylinder 19 journalled in a circular opening in the base 12, and an eccentric cam or crank pin 2o integral with the cylinder 19 and received in a bushing 21 in an elongated slot 22 of an intermediate portion `of the lever 16. As the eccentric is rotated by the gear train 17, the lever 16 is oscillated about the pin 14 in a plane parallel to the base 12. The ratchet wheel 25 is mounted on the main pin 14, immediately above the lever 16, for rotation selectively in opposite directions. Circumferentially spaced lugs 26 are integral with a top face of the ratchet wheel for a purpose to be described hereinafter. V-shaped ratchet teeth Z7 are on the circumferential edge of the ratchet wheel.
The driving pawl 30 is pivotally mounted on a free end of the lever 16 4by a suitable driving pawl pin 31 retained in aligned holes in the lever 16 and the driving pawl 30 in any suitable manner as by split washers in grooves of opposite ends of the pin. The driving pawl oscillates with the lever 16 and is pivoted between two positions, and more particularly lbetween a rst position in which a first detent 32 operatively engages the ratchet teeth 27, as shown in FIGURE 1, and a second position in which a second detent 33 operatively engages the ratchet teeth 27, for selectively driving the ratchet wheel step-by-step selectively Vin opposite directions, thereby providing driving means for moving the ratchet wheel in opposite directions responsive to oscillating movement of the lever 16 by the eccentric 1S. The driving pawl 30 has a finger 34 extending away from the dri-ving pawl pin 31 with respect to the main pin 14 for receiving an end of the spring 57, as will be more fully described hereinafter.
The abutment 35 on the driving pawl 30 and abutments 36 and 37 on the ratchet wheel are provided for moving the driving pawl from one of the two driving pawl positions to the other position in response to rotation of the ratchet wheel 25 a predetermined amount in either direction by the driving pawl 30. The abutment 35 is integral with the driving pawl 30l and is positioned toward the main pin 14 with respect to the driving pawl pin 31 for engagement with the fixed abutment 36 which is integral with the ratchet wheel for moving the driving pawl from the first driving pawl position to the second driving pawl position. The abutment 37 is adjustable and is provided by a rfree end of an arm 38 received on the top surface of the ratchet wheel 25 and having an opposite end pivotally mounted on the main pin 14. A split lock washer 39 is `detachably received in a groove in the free end of the main pin 14 for retaining the lever 16, the ratchet Wheel 25, and the adjustable abutment arm 38 on the main pin 14. The outer end of the resilient leaf spring type abutment arm 38 may be raised for selective positioning of a finger 40 thereof between any of the lugs 26 on the ratchet wheel, thereby adjusting the amount of rotation of the ratchet wheel in either direction required to reverse the position of the driving pawl 30. As shown in FIGURE Il, the fixed abutment 36 has just engaged the driving pawl 35 and is about to move the driving pawl from the first driving pawl position to the second position as illustrated in FIGURE 3.
The holding pawl 43 is pivotally mounted on the 4base 12 by means of a holding pawl pin 44 suitably secured to the base 12. The holding pawl 43 is pivotal between two positions, and more particularly between a first position in which a first dete-nt 45 engages the ratchet teeth 27, and as shown in FIGURE 1, and a second position in which a second detent 46 engages the ratchet teeth 27 for selectively holding the ratchet wheel against rotation, and for positioning the ratchet wheel for step-by-step rotation by the driving pawl, thereby providing holding means for regulating the movement of the ratchet wheel 25 is opposite directions. The holding pawl has an abutment in the form of a rod 47 extending through a slot 48 in the base 12 and engaging a resilient actuator 49 of a conventional double pole double-throw electric switch y50 and providing means for moving the actuator 49 in response to movement of the holding pawl 43 between the two holding pawl positions. The switch has a movable contact 51 resiliently mounted by a spring 52 for over-center snap` action `between fixed contacts 53 responsive to movement of the resilient actuator 49. The holding pawl 43 has a nger 55 extending toward the ratchet wheel 25 with respect to the holding pawl pin 44, and spaced above the driving pawl finger 34 as seen in FIGURE 2, for receiving the end of a spring, as will be more fully described hereinafter.
As indicated briefly above, the driving and holding pawls are concurrently urged to their respective first and second positions by a C-shaped spring 57 having opposite ends '58 and 59 in the form of transversely extending fingers, pivotally respectively received in holes in the driving pawl finger 34 and the holding pawl finger 55. Spring 57 is of the type in which its outer ends 58 and 59 are biased away from each other. The finger holes are so arranged to pass each other in opposite directions as the pawls move together between the first and second pawl positions. Thus, the spring 57 provides the means for 'urging the driving pawl and the holding pawl detents into selective engagement with the ratchet teeth and, responsive to transfer of the driving pawl from either one of the two driving pawl positions to the other position, transfers the `holding pawl selectively to the two holding pawl positions, or effects concomitant movement of the pawls from the first or second positions to the other positions.
To summarize the operation of the water meter regulator 10, as the -gear train 17 is driven in accordance with the water flow, the eccentric 18 is rotated thereby oscillating the lever 16 and the driving pawl 30. With reference to FIGURE 1, the driving pawl detent 32, in a first position, engages the ratchet teeth 27 for driving the ratchet wheel in a counterclockwise direction. When the fixed abutment 36 on the ratchet wheel engages the abutment 35 on the driving pawl, the driving pawl is moved from the first position to a second position, as illustrated in FIGURE 3, wherein the second driving pawl detent 33 engages the ratchet teeth 27 to drive the ratchet wheel in a clockwise direction until the adjustable abutment 37 on the ratchet wheel 25 engages the driving pawl abutment 35 to again move the driving pawl to the first position. As the driving pawl moves between its two positions the C-shaped spring 47 is moved over-'center thereby concomitantly selectively urging the holding pawl into each of its two positions.
Having described my invention as related to the embodiments shown in the accompanying drawings, it is my intention that the invention be not limited by any of the details of description, unless otherwise specified, but rather be construed broadly within its spirit and scope as set out in the accompanying claims.
